Nothing is truly NSA-proof or hacker-proof, but WireOver wants to offer you more security than Dropbox, Google Drive, or Skydrive. The Y Combinator startup just emerged from stealth with a desktop app that lets you send files of any size for free. And for $10 a month, your transfers get end-to-end encryption so only the recipient can open them. WireOver can’t even look at what you’re sending.

If you just want to send huge video files or photo collections to friends and aren’t worried about encryption, WireOver is totally free for unlimited file-size sharing. But its premium level of privacy could be a big draw for anyone with sensitive files to send.
